Calendar won't Subscribe from Web

Jeff Rogers 0

Hello, we are attempting to "Subscribe from web" to a calendar which fails on the web and Outlook app but works on other calendars (Apple, Google). What settings in the MS365 Admin Center control permissions for external calendar feeds? We have tried on different PC's and browsers - as per M365 help suggestion.

This is the error that we get from Outlook via Chrome (see bottom of screenshot):

and this is what happens in the Outlook app

Same URL works in Apple and Google calendars.

Screenshot of Exchange Admin Center (perhaps we need to add the URL here?):

Hi @Jeff Rogers ,

You can add online calendars from Google and others right into Outlook. There are two methods. See this article: https://support.microsoft.com/en-us/office/import-calendars-into-outlook-8e8364e1-400e-4c0f-a573-fe76b5a2d379

Can you follow the steps in the above article to subscribe to Google Calendar in your outlook?

How did you download the ics link? Based on my searches, the possible cause of the issue is unreliable subscription links, "Subscribe from web" option in OWA error.(Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.)

We have a big need for our official holiday calendars (one for each of our countries where we operate - which is around 150) to be available to be added to user's Outlook calendars. We have the holiday calendars as ICS files stored on our SharePoint Intranet - however, "Subscribe from web" does NOT work when the ICS file is living on SharePoint. Also, the URI webcal:// doesn't work, even if the ICS file is stored on a public website.

There is no documentation on this fact, from what I can see so far. It would be great to have this ability access ICS files on M365 (i.e. SPO).
